Netgear R7800 Dropping connection every few minutes

Starting several days ago my nighthawk r7800 has been dropping all connections on both the 2.4ghz and 5ghz bands varying in intermittence from 1-15 minutes, and occuring on all devices, even after a SSID change and only 1 device connected(tried two difference laptops this way to rule out the 1 device, same issue), and even after factory resets of both my modem and router. When this occurs the lights do not appear to change at all on the router, power is steady, internet light blinking, 2.4 and 5ghz lights blinking, and the wifi on/off and wps buttons lit steady. We just moved 3 weeks ago but this was not occuring for the first two weeks so believe its unrelated. Firmware tells me it is up to date V1.0.2.60. The modem is a netgear CM500 and its lights stays normal when it occurs as well and no events are logged in the modems event log(all lights lit steady except link light which is blinking) so pretty sure it's the router. I also checked the signal strength to modem and had around 0mdb+/- 1mb downloads and 51mdb+/-1 uploads, hearing that above 50 may be high(dont think it is for that modem) i removed the splitter and have 6.5 +/-1 mdb down and 46+/-1 mbd up after and seemingly no change at all to the problem. Disconnect is confirmed by often but not always seeing the wifi connection drop then reconnect on my laptop(Doesn't drop visibly in windows 10 every time, have also seen just 1 line of request timed out in cmd prompt then back to normal)

(above pings occured 14:19:xx, below log taken awhile after,  the DHCP IP to mac adress events occur when the interuption is long enough to drop the connection from my laptop i believe, and i do not think the first remote access caused a interuption but the one at 14:35:47 did occur around or at an interuption will continue to see if theres a link but don't think so, but do not know what that remote access is)

I really don't know what to do at this point, I'm starting to contemplate replacing the router but will wait till someone more knowledgable reccomends that... it is between 1-15minute intervals nonstop never a respite from that, but started all of a sudden out of the blue first two weeks at this new address were fine, factory resets and dropping to 1 device and then changing that 1 device to be sure have not isolated it, i'm out of ideas! thanks again for any help!

Re: Netgear R7800 Dropping connection every few minutes

It's the firmware. Netgears last 2 releases .58 and.60 have connection issues and latency problems. This has been talked about on verious forums. The solution right now is to roll back to version .52 or use Voxel's firmware .62. untill NG releaes a fix.

Re: Netgear R7800 Dropping connection every few minutes

with .52 all problems seem to be resolved, haven't seen a ping over 40ms in 20 mins now...
Thanks for the help, I had factory reset the router and updated the firmware to newest version awhile ago so this makes sense... spent 6-10 hours trying diferent things and learning about troubleshooting networks so thanks for that netgear...

Re: Netgear R7800 Dropping connection every few minutes

Thank you both so much; I have the exact same issue, been researching and troubleshooting for months.

Here's a candid question though: isn't there a security risk associated with using an older firmware?

Re: Netgear R7800 Dropping connection every few minutes

Looks like V1.0.2.62 is out. I just tried it (was on .52 previously for the reasons above). This new version seems just as bad if not worse. I even did a factory reset. Has anyone else tried V1.0.2.62?

Re: Netgear R7800 Dropping connection every few minutes

bmurmistro,

 

Myself and others have been running 1.0.2.62 without this packet loss for some time.   

Are you saying you get packet loss with this version also  but not .52 ?

Re: Netgear R7800 Dropping connection every few minutes

I'm on .62 as well and everything works with no issues. Some people also report the 5 GHz issue of .58 and .60 is fixed. I can't confirm or deny as I don't use that band

Re: Netgear R7800 Dropping connection every few minutes

 

@RMinNJ yes, although I suspect my issue might be slightly different. With .52 I would occassionaly lose connection but it would eventually recover. With .62 I lose connection every 30 mintues or so (does not recover) and in order to fix it I either have to reboot my modem or just simply unplug and plug back in my internet line into the router and I'm good. I suspect it could simply be a bad eithernet cable. I will do some experimenting today and see if I'm able to track it down.

Re: Netgear R7800 Dropping connection every few minutes

Thank you @bmurmistro for the heads up on the new .62 firmware.

 

My initial feedback: the periodic wireless drop issue seems vastly improved, but not entirely gone:

  • Used to be ~10 seconds of drop every ~10 minutes (with fw .58 / .60)
  • Now with fw .62 I observe ~3 seconds of higher pings (100-200ms) every 3 minutes (quite consistently). No full drop. 🤷🏻‍♂️local ping test on firmware 1.0.2.62local ping test on firmware 1.0.2.62

     

Test method used: pinging a wired machine on the local network while laptop is connected via 5 GHz.
